Life Cycle Assessment of a Coke Cleaning Agent

Abstract

The life cycle assessment of the coke cleaning agent developed by a university-enterprise cooperation project was conducted. This cleaning agent has the characteristics of phosphorus-free, environmentally friendly, and broad market prospects. The life cycle assessment of the established model showed that the GWP of producing 1kg of coke cleaning agent is 1.19 kg CO2 eq, PED is 13.17 MJ, WU is 186.74 kg, AP is 3.63E-03 kg SO2 eq, ADP is 7.75E-05 kg antimony eq, EP is 1.30E-03 kg PO43-eq, RI is 1.16E-03 kg PM2.5 eq, ODP is 4.63E-06 kg CFC-11 eq, and POFP is 1.85E-03 kg NMVOC eq .The uncertainty of the results is between 4.20% and 24.05%. The carbon footprint (GWP) analysis showed that the production process of isotridecanol polyoxyethylene ether, isopropanol, fatty alcohol polyoxyethylene ether M and isodecanol polyoxyethylene ether contributed significantly. The average sensitivity analysis showed that the most influential processes were sodium lauryl amphoacetate, isopropanol, and tripropylene glycol methyl ether.

Formulation improvement of a concentrated enzyme detergent for high-speed rail trains through life cycle assessment methodology

“…At present, the cleaners on the market are mainly high pH alkaline cleaners. Although the formulation of ordinary cleaners is stable, they are not specific designed (Gong et al, 2022 ). For example, washing with hard water will be worse, ( i.e.…”

“…At present, the cleaners on the market are mainly high pH alkaline cleaners. Although the formulation of ordinary cleaners is stable, they are not specific designed (Gong et al, 2022). For example, washing with hard water will be worse, (i.e., the dirt will not be cleaned thoroughly), and it will easily cause environmental pollution and other problems (Danby et al, 2018;Li et al, 2021).…”
